Graphical abstract
Figure 1
Figure 1
A 12-lead ECG demonstrates normal sinus rhythm with frequent PVCs that have an inferior axis and a left bundle branch block morphology.
Figure 2
Figure 2
Two-dimensional TTE, apical 2-chamber (A) and apical 2-chamber (B) views in diastole (left) and systole (right), demonstrates the normal global LV systolic function with a focal LV apical dyskinetic outpouching segment with a relatively wide neck (red arrows).
Figure 3
Figure 3
Rest SPECT MPI with short-axis (SAX; top two rows), vertical long-axis (VLS; third row; apical 2-chamber equivalent), and horizontal long-axis (HLA; bottom row; apical 4-chamber equivalent) displays demonstrates an apical perfusion abnormality with an outpouching seen particularly in the HLA views with radiotracer uptake seen within the walls of outpouching myocardium (red arrows).
Figure 4
Figure 4
Cardiac computed tomography multiplanar reconstruction images in representative apical 4-chamber (left), apical 2-chamber (top right), and apical short-axis (bottom right) views depicting the aneurysmal outpouching at the apex (red arrows) and anterolateral (yellow arrows) myocardial wall segments with a relatively wide neck and smooth transition from the adjacent normal myocardium to the thinned aneurysmal wall. LA, Left atrium; LV, left ventricle.
Figure 5
Figure 5
Three-dimensional CCT volume-rendered reconstructions demonstrate the complex LV aneurysm comprising 2 separate but interconnected outpouchings at the cardiac apex (red arrows) and distal anterolateral myocardial wall segments (yellow arrows).
Figure 6
Figure 6
Cardiovascular magnetic resonance imaging, LGE sequence 4-chamber display, demonstrates the complex LV apical aneurysm comprising 2 interconnected, focal, thin-walled outpouching myocardial segments with a thin subendocardial layer of LGE lining the aneurysm walls.
